well, presentation is half the battle. my token of advice is to make the fish tanks look clean, the fish well fed, the glass free of algae, etc. like, for africans, use black sand and white aragonite gravel with a black background. make sure the employees know what they're talking about with fish keeping. pretty cool gig i might say, too. id worry about saltwater later on afetr you have straightened out all the other sections that need your attention (the id cards, employees, tank stocking, replenishing supplies, etc.). hope that helps...
